STOPPING AND STARTING MECHANISM FOR TICKETING MAonINEs.

' Original application filed December 15, 1923, Serial No; 680,885 1 Divided and'this'application filed I January 26, 1926.

My invention relates to certainimprovements in ticketing machines, for which Letters Patent were granted to me on the 17th- .day of October, 1922, No. 1,432,554.

The object of the present invention isto im prove the construction of the starting and stopping mechanisms of the machine. 2 In the accompanymg drawings: I

Fig. 1 is a side view of my improved ticketing machine;

Fig. 2 is a rear end view of the same; and r Fig. 3 is a front end vlew.

The present application is a division of an application filed by me on December 15, 1923, Serial No. 680,885, for improvements in ticketing machines, which resulted in Patent No. 1,574,391, dated February 23, 1926.

1 is the base of the machine. 2 is an electric motor mounted on the base. 3 is the mam frame of the machine, which is also mounted on the base 1. 4 is a longitudinal cam shaft, which is mounted on the frame 3., 5 is a transverse shaft which is connected to the motor shaft 2 by a coupling 5 On the shaft 5 1s a worm 6, which meshes with a worm-wheel 7 mounted loosely on the cam shaft 4. On the cam shaft is a cam 8, which actuates a slide 45.

9 is a. cam which actuates the printing mechanism 50. 10 is a cam which actuates the shears 57 and the tension mechanism at the head of the machine. The cam shaft 4 extends into the head 11 of the machine and actuates the needle 13 and presser-bar 12.'

A longitudinal shaft 25 is mounted in bearings on the underside of the base. On the rear end of the shaft is a pinion 26, which meshes with the teeth of a rack 27, arranged to slide in the bearing 28. Therack is con-j nected to the pivot 29 on an arm of a disk 30. On the forward end of the shaft 25 is a gearwheel 24, which meshes with a pinion 23. This pinion is mountedon a stud 21 on whlch is a gear-wheel 21 having a pin 87 which is engaged by a latch. This II1OhaI1lSH1flClL11 ates the looper mechanism and the feed-bar of the machine.

Details of the stitch-forming mechanism 7 are fully set forth in the above-mentioned Patent No. 1,574,391, dated February 23, 1926. s

The pinion 26 is loose on the shaft 25 and has a disk-26 secured thereto. On this disk the disk 30. On thewhich is arranged to chine, and held in normal wheel 7.

the shaft 25 is intermittently turned in one direction only. v nthedisk 30 is a-pawl 31, which pivotedat Attachedto the pawl is a spring The otherend of the spring is secured to pawl31 is a-heel 31 come in contact with ya stop 34, pivoted at 35 to the frame position by a spring 35.

This'lever is pivoted to the frame at 39 and has a push-pad 40. A spring 41 is tonnect tends to hold the rod 37 and the stop 34 in the position shown in F lg. 1, the stop being in engagement with the pawl 31.

When the lever 38 is pushed, the rod 37 is moved in the direction of the arrow, Fig. :1, and turns the stop 34 on its pivot clearof .the pawl 31, ratchet-wheel 36,

heel 31 of the pawl comes in contact with the stop 34, which returns to its normal position as soon as the operator releases the push-lever. This stops the mechanism of the machine, which cannot start again until the operator pushes the lever.

The cam 8 on the shaft 4 has a scroll slot in which extends a pin 42 on a lever 43 pivoted to the frame at 44. The lever 43 is connected to the slide 45 by a link 46. The slide is re ciprocated by the cam 8 over the bed 47:0n which the strip of tags is fed. '7 V On the lever 43 is an arm 51, which extends 37. under whichthe arm 51 travels as the The arm 51 lifts the bar'37 out of engagement with the stop 34, and allows the stop to return to its normal popawl, should the operator fail to release the lever in time.

Connected to the outer end of the arm 81 is a rod 84 that extends to a latch 85 which is pivoted at 86 to a projection on the base 1. This latch engages a pin 87 on the gear Wheel 21 and stops its rotation at a given point. The cam 83 controls the movement of the latch so as to release the gea1'-wheel at the proper time i I claim:

1. The combination of a driving shaft; a worm thereon; a cam shaft; a Worm Wheel loose thereon; a ratchet Wheel on theivorm Wheel; a disk on the cam shaft; a pawl piv otally mounted on the disk; a longitudinal shaft; ap-inion loose on the shaft; a pawl connecting the pinion With the shaft; a bearing on the shaft; and a rack bar, pivoted to the disk on the cam shaft arranged to slide in the bearing, said bar having teeth meshing with the teeth of the gear Wheel loose on the V longitudinal shaft.

2. The eomblnation in a ticketing machine,

of a frame; a cam shaft; operating means for said shaft; a pivoted stop arranged to control the movement of the operating means; a longitudinally movable bar for moving the stop; an operating lever for the bar, saidbar having a cam; a rotary cam on the cam shaft; a lever pivoted to the frame andactuated by the rotary cam; and a slide connected to the lever said lever having an arm extending under the bar to elevate the bar on the movement of the lever toafree the stop.

3. The combination of a driving shaft; a Worm thereon; a cam shaft; ajworm Wheel loose thereon; a ratchet Wheel on the Worm Wheel; a disk on the cam shaft; a pawl piv otally mounted on the disk; a longitudinal shaft; a pinion lose on they shaft; a pawl 'connecting the pinion with the shaft; a bearing on the shaft; a rack bar, pivotedto the dish on the cam shaft, arranged to slide in the bearing, said bar having teethmeshing With the teeth of the gear Wheel loose on the longitudinal shaft; and release mechanism at the opposite end of the longitudinal shaft arranged to stop the rotation of the shaft at a given point.
